SPECIFICATION forming part of Letters Patent No. 738,783, dated September 15, 1903. Application iilecl August l, 1902. Serial No. 117.924. (No model.)

To @ZZ rah/071e t may concern,.-

Beit known that I, GEORGE H. ELLIS, of Chicago, in the county of Oook and State of Illinois, have invented an Improved Flax- Straw-Preparing Machine, of which the following is a full description, reference being had to the accompanying drawings.

The purpose of this invention is to receive aX-straw in bundles as formed by harvesting-machines, comb and clean the straw, sever the heads, bind and deliver the combed and cleaned straw inbundles, and thresh, clean, and deliver the seed from the tops and combings. The object in view, as is well known, in thus handling the straw is to avoid breaking and otherwise injuring it for fiber uses and at the same time have a capacity coinparable to that of an ordinary grain-th resher.

Figure 1 is a right-hand side elevation of the machine; Fig. 2, a vright-hand sectional elevation of the machine; Fig. 3, a plan View .with combing-arms removed; Fig. 4., a sectional right-hand side elevation of the rear set of combs and parts that coperate therewith. Fig. 5 is a right-hand side sectional elevation showing the mechanism provided for spreading the straw fed by the feedingchain and by meansof the conveying-belts passing itin the form of a continuous swath to the combing devices. Figs. 6, 7, and S are sectional end views showing the relative positions of the cleaning-forks with the strawcarrying chains, the cutter for severing the heads, and a pair of rollers for crushing the bolls of flax in the straw. Figs. 9 and 10 are detail views showing the construction of the `trucks or antifriction-rollers against which bears the chain that conveys the swath of i straw. Figs. 11` and l2 are detail views of the cutter-head. Fig. 13 sho-ws the arrangement of the driving belts and chains. Fig.

i 14 shows detailsof crushing-rollers adjacent to the grasping and` conveying chains; and Fig. 15 is a transverse section of the grasping-chain, showing the shape of two coperating links.

i My machine for convenience is mounted upon trucks adapted to support it steadilyT and render it portable.

various working parts `may be of anyform adapted to receive shaft-bearings and vari,-

The frame for the ous other supports. Sumce it to say that the parts A represent the sills.

B is the housing for the working parts at the lower portion of the machine.

In order that the device may be best understood, it will be described in detail, beginning with the primary feeding devices.

O is the receiving-table, preferably. up- Wardly inclined toward the machine, and mounted thereupon and passing over the upper surface thereof are the toothed endless feeding chains or belts c. This toothed belt is moved slowly by pulleys c on "the shaft c2. This shaft c2 is given rotation by a chain c4 thrown over the sprocket-wheel c5, which sprocket-wheel may be given motion from the shaft D3, as shown in Figs. 1, 2, and 3. Slots are provided in the table at its upper ,edge to receive the sprocket-wheels c' and through which the toothed belt c may recede. The purpose of these endless conveyers is to deliverth'e bundles of dax-straw to the spreading-wheel d8 and the conveying-belts after they have been thrown on the feeding-table and their bands severed automatically or otherwise, and thus present a uniform iiow of straw to the machine. The shaft of2 is supported at each end on pillow-blocks, which are'securedto the framework. A board c7 is provided on the table C on the left-hand side, against which the head ends of the bundles are placed when feeding same to the machine.

Upon the framework supported in suitable bearings are the shafts D, D', D2, and D3, and upon each of these shafts are the two pulleys `d, d', d2, and cl3, respectively, as shown in Figs. 2, 3, and 5. Around the pulleys ld and cl2 are thrown the two endless conveying-belts d4 d5, and around the pulleys d and dare thrown the two similar opposing beltsd6 and 017 dl, being directly beneath and cop-erating with the belt d5, `but not shown inidrawings. In the same way the belts d4 and d6' coperate. The shafts D and D3 are journaled in bearings which are spring-supported beneath, as shown in Fig. 6, thus admitting of adownwardly-yielding movement when an unusually heavy swath of straw passes between the said conveying-belts. Upon the shaft Dis any part of the machine, but preferably from h TOO toothed wheel Z9 near their middles, which re- Volves in the direction indicated by the arrow in Fig. l. By this wheel they are moved downward and fed between the conveyingbelts d4 and d5 above and d0 and 17 below. By means of the toothed wheel and the belts the straws are formed into what may be regarded a swath. 1 v Y EA and E are the upper loops, and E2 and E2 are the lowerloops, of the grasping-chain, earried and driven by the special sprocket-wheels E0. The loops E and E2 are arranged in the same vertical plane and are adapted to cooperate, as hereinafter more fully set forth. The same arrangement also applies to the loops Eand E9.

The grasping-chain is driven as follows: Through the belt X and suitable pulleys motion is communicated direct from the cylinder-shaft M to the shaft X2, as shown in Figs. 2 and 13. By suitable gearing the shaft X2 imparts motion to the shaft E9, which in turn by gearing imparts synchronal rotation to the shaft E10. The shafts E9 and X2 are journaled in suitable bearings on the frame, while the shaft E10 journals in boxes which are secured to arms E, swinging from the center of the shaft E9, and may be considered to be held rigidly by suitable means. Alsojournaled in bearings on the frame and lying in the same horizontal plane as the shaft E9 are the shafts E9, E7, and E0, while similarly located relative to the shaft E10 are the shafts E5 and E4, also journaled in bearings on the frame of the machine. The shaft E10 serves as the drivingshaft for the two upper loops E and E of the grasping-chain through the instrumentality of the grasping-chain itself and thesprocketwheels E0,which are rigidly secured to the several shafts, the shaft E5 of course carrying two sprocket-wheels, one for the forward loop E and one for the rearward loop E. (Shown in Figs. 2 and s.) The shaft E9 drives the lower yrear loop E2 of the grasping chain through the sprocket-wheel E0,rigidly secured thereto, the forward end of said loop passing around a similar sprocket-wheel on the shaft E7. As indicated inthe drawings, Fig. 2, the lower loops of the grasping-chain overlap each otherforapurpose'hereinafterexplained,leaving the lower forward loop E2 to be independently driven. This is accomplished by a sprocket chain passing around sprocketwheels on the shafts Ei'and E8, said sprocketwheels and chain being located on the ends of the projecting shafts on the left-hand side of the machine, as shown iuFig. 3.

The shaft E0, bearing the sprocket-wheel E0, which carries the forward end of the loop E2, is journaled in slidable boxes, the pull of the grasping chain being counteracted by the springs F, connected to said slidable boxes and some fixed part of machine, so that by adjustment of these springs any desireddegree of tension in the loop E2 of the graspingchain may be secured. The loops E and E3 of the'graspingchain may be spring-tightened in the same manner, but are shown mounted in rigid bearings. The bearings in which journals the shaft E10 are supported by swinging arms E11, pivoted on the shaft E9, as shown in Fig. 1. These arms E11 are adjustably secured in position by means of the rearwardlyprojecting arms y, integral with the bearings of the shaft X2. The arms y being provided with arcuate slots y', which are adapted to receive bolts y2 on the arms'E11, will permit the said arms to be swung rearwardly the desired amount and secured and in this way providing adjustment for the tension of the loop E. Thus adjustment may be made when as-v sembling for fitting the chains and further adjustment to prevent sagging and to compensate for wear. As the function of these loops of grasping-chain is to retain and convey the flaX-staw while having the heads cut offand the straw combed and cleaned of weeds, grass-seed, bolls, and other undesirable material, then in order to insure a continuousand positive transmission of said flax-straw the two lower loops overlap each other, so that for a short space the flax-straw is engaged by the four loops of the said chain; also, in addition to the above-specified arrangement of the several loops the two forward loops E and E2 operate in a vertical plane parallel with the plane of the two rear loops E and E3, butsufciently removed that the straw will"be grasped by the two latter loops at a new or combed portion of the stalksof flax-straw and leave the uncombed portion, which had been held between the first two loops, free to the subsequent action of the second set of combs.

' It will be observed from an inspectionof Figs. l and 2 that the ends of the Lipper and lower loops of the grasping-chain are notn vertically coincident. The effect of such an arrangement is to avoid .the interference of the long links as they pass around the sprocketwheels E0 by allowing the ends of the links to be either beyond a point where they will come in contact with the coacting chain or the end of said links will come in contact with a iiexible portion of the said coacting loop of thegrasping-chain. Thisgrasping-chainconsists of links of considerable length and width ICO 'Ilo

serrated on the surfaces which come in contact with the straw, as shown in Figs. 3 and ment of the said frame.

tooth of the single-serrated row above and E? are the teeth of the double-serrated row below,with the depression between. This depression receives the points of the single-serrated teeth in the links of the chain above, and thus form jaws which will afford a twopoint support below and a one-point support above for'the dax-straw lying between. The

upper or engaging portion of the lower loops is held up rigidly in working position and `also in alinement by a series of antifrictionrollerse, which journal on bearings secured to the `bar e',which is in turn rigidly connected to the frame of the machine, as shown in Figs.

l, 2, or 4. The lower or engaging portion of the upper loops-is held yieldin'glyin working position and in contact with the engaging part of the `lower loops by devices such as `shown in Fig. 10. Here the rollers e2 are journaled on a frame e3, each frame supporting four rollers. i Between the bars c4 and e5, Fig. 3, are riveted or otherwise secured. a transverse connecting member e6, as shown in Fig.

i 10. `A bolt e7, passing through a centrally-ld cated hole in this member and upwardly through a corresponding hole in the frame e3 and receivinga compression-spring es, serves to hold the frarnee?` infeontact with the con-f necting` member e6 and yet permit an upward sure `can be obtained between the engaging portions of the several loops of grasping-chain, and in this way the dax-straw or material operated upon can be held firmly between the serrated links of the cooperating loops of the j grasping-chain. The'forcewhichthesespings exertto press the linksof the upperV loop upon those of the lower loop operates not so much by thedirect pressure between them to retain the flax-straw as by the wedging action of the` straws between the adjacent teeth and not the opposing teeth.

Located in suitable bearings on the frame is the cutter-shaft G, carrying the rotary cutter h3, as shown in- Figs. 3 and 7 and the cutter-head in detail'in Figs. 11 and l2.

This rotary cutter is arranged to engage and sever i the heads of theflaX-straw as it passes between the loopsE and E2 of the graspingchain. The cutter-shaft G is driven by the i pulleyg, secured to said shaft and engaging with the belt X',` the location `being shown j in Figs. 2 and 3 and the `method ot' driving in Figs. 2 and 13. The detail construction of the cutting-head is shown in Figs. 1l and 12,where h2 h2 represent the cutting "blades or` knives, secured bybolts or otherwise to the 'head-piece h3, which in turn is rigidly secured totheacutter-shaftG. As shown by the draw` shown in Figs. l, 2, and 4.

ings the cutting edges of the blades h2 hzpro- `ject somewhat from and in advance of the arms of the head-piece h3,so that when rotated at a high speed the straw carried againstthe cutter' by the grasping and conveying chains will have its heads severed when passing the said cutter.

H H, Figs. 3 and 14, represent a pair of rollers secured to the shafts 7L h. They may be driven by a sprocket-chain thrown around a sprocket-wheel h on the lower shafth and a in. It will be observed by inspection of Fig. 3 that the above-mentioned rollers are placed neai` the forward end of the rear loop of the grasping-chain, so that they will operate upon the straw before it passes to the second set of combs, thus allowing the straw to be combed after the seed-bolls have beencrushed.

The combs I and I are clearly shown in Figs. 1, 2, and 4and in detail in Figs.`7 and 8. These combs are arranged in two sets, a forward set Ladapted to operate upon the butts of the flax as itpasses between the two forward loops, and the rear set I', adaptedto operate upon the opposite end of the straws of the roo swath as it passes between the two rearloops.

As before explained, the forward loopsand rearward loops operate in planes slightly removed frein each other, so that the combs will in the two operations clean the entire length of the stalks. These two sets of combs l I and l' are driven by crank-shafts z' and fi',

respectively, longitudin ally arranged with respect tothe frame of the machine.V The transverse shaft l2 through a bevel-gear andlpinion transmits motion to the crank-shaft t', and

through means of sprocket-wheels and chainV j 6, a secondary shaft v7, gear is, and pinion if motion is imparted to the crank-shaft fi', as The transverse shaft l2 is driven by the pulley I3 on same, engaging with driving-belts X and X', Figs. 1

and 13. The.cranlr-sl1afts t' and c" are mounted in suitable bearings on the upper portion of the frame and are preferably four-throw,

the cranks being arranged opposite.` In `the wrist ofeachcrankjournalis pivotally mounted the lever i?, the longer part of "the: lever being below the journal. upward extension of the lever 712 is pivoted an On the end of the arm fis, the other end being pivoted to aiixed support i4. To the lower or longend of these `levers i2 are secured the lcombing-teethz'f, consisting of two rows of round sharp-pointed teeth, orthey may be made of thin fiat plates with the edges sharpened and tapering to a point below, while the Iineofadvance teeth will permit the teeth to be inserted in the straw Very close to the grasping -chain and drawn downward and away from same, thus cleaning and combing the straw and yet not breaking it. t

Arranged at the delivery end of the machine and adapted to receive the headless and combed flax-straw from the grasping-chain is the automatic binder J, driven by means of a sprocket-chain connection with the shaft E9, as shown in Fig. l. The flax-straw is delivered on the binder-table j of the binder J from the grasping-chain, and the binding operation is in all respects like that on the ordinary harvester, the flax being bound in bundles and delivered tothe rear of the machine.

Shown in Fig. 2 extending transversely the widthof the machine and longitudinally almost the entire length is the platform 7c. At

the' forward end of this and slightly below is 1 a roller secured to the shaft K, and similarly located at the rear end is a roller secured to the shaft K. Both the shafts K and K/ journal in bearings secured to the main frame. A sprocket-wheel concentric with the shaft K and secured to same engages with the sprocket-chain L, which will be more fully described later. Over the rollers in these two shafts K and K passes the endless conveyer k', consisting of a sprocket-chain provided with projections or ears to which are secured slats, and the conveyer rollershafts being provided with sprocket-wheels to engage said chain. Through the sprocket-chain L and its engaging sprocket-wheel on the shaft K the shaft K, the roller secured thereto, and the conveyer c'are driven, the conveyer-slats sliding forward over the top of the platform k and the slack side of the conveyer being supported in its return by the slide 7a2. It is obvious, of course, that were the cylinder placed ina position adapted to receive the` tops direct from the cutter h3 then it would be possible and practical to dispense with the conveying mechanism. It will thus be seen that all the combings, cleanings, tops, and seeds that fall from the cutter g, the combs I and I', and the rollers H H will fall down upon the platform 7c and bemoved by the endless conveyer 7c to the forward end of said platform and delivered over its end for the subsequent crushing, threshing, and cleaning, which will now be described.

The cylinder-shaft M of the threshing-cylinder m is journaled in bearings rigidly secured'to the frame of the machine, the location being at the forward end, slightly in advance of the shaft K and'some distance be-.

low, or in such a position as to adapt it to receive the material delivered from the conveyer 7c'. The threshing-cylinder, as is usual in .thisclassof machines, receives its power dieither end and within the frame are the cylber in this instance-are secured. To these bars are secured ribbed plates, the ribs eX- tending at opposite angles 'to the axis of cylinder on alternate bars, following a type well known. The/two sets of cylinder-concaves N N are located directly beneath the cylinder and consist of a series of light bars bolted together and teeth or lugs on these bars to hold them at some distance apart. This presents, therefore, a broken concave surface to coperate with the cylinder and sufficiently open to permit the seeds from the broken flax-bolls to pass through. As I claim nothing novel in this cylinder and its concaves, the general description just given will be sufficient for these parts.

The description of other features used in my invention, necessary but not new-such as the fan, blower, riddles, agitator, &c.--will be treated in the same general way.

The boards n and n2, extending from the concaves N upwardly and'forwardly, serve to close the forward end of the machine and deflect the material thrown by the conveyer 7c to the pair of rollers O O and the cylinder fm. This pair of rollers O O are so situated as to operate upon this material thrown by the conveyers just before it enters the cylinder and crush the bolls, thus rendering more effective the subsequent action of the cylinder and other parts operating to separate the flax-seed from the straw. These rollers O and O, journaled in bearings on the main frame and driven from the shaft D or some other convenient shaft, may be provided with longitudinal grooves and elevations to increase their efficiency, if desired, the elevations in one roller adaptedl to mesh with a groove in the corresponding roller, thus insuring va more effective breaking up of the flaX-bolls. In passing through the rollersO O and the cylinder m most of the seeds are separated from the straw, the seeds dropping through the cylinder-concaves N N down to the riddles P and the straw containing unseparated seed being delivered from the cyl- IOO IIO

inder to the agitators S. The s top fa', similar Y to n and n2, deflects the seed and other fine material from below the cylinder and concaves to the riddles P.,

Forward of and slightly below the riddles P is the fan r, suitably incased and secured to the fan-shaft R. by means of belt-and-pulley connection with the cylinder-shaft M. The riddles or sieves P are given a reciprocatory movement by the eccentric-rods r', actuated by eccentrics on the fan-shaft R. The rddles,preferably three in number, are arranged with the coarsest sieves above and the finest below, the rear end sloping slightly downward. The rear ends of the agitators S are mounted "on rocking arms s' and are slightly higher than the front end. The forward ends of the agitators S journal on and are supported by a The fan-shaft Ris driven 6o i upon, and convey itto and from the several e crankshaft S, the cranksbeing alternately oppsite.` The crank-shaft S', journaled in bearings on the main frame, is driven by a cross-belt and suitable pulleys from the fanshaft R. The motion of the upper agitators being to therearward, as is usual where such devices are used, the effect will be for the teeth above to work all material delivered thereon to the rearend, while the seed and fine substance contained therein will drop to the fixed table szand be worked to the forward end of said table by the teeth on the lower side of' the agitators. Here it will fall to the riddles P, where it is further cleaned and separated. A blast of air from the fan passes through the riddles, as is customary in threshing-machines, to'assist in the cleaning and separating process. The cleaned seed passes through the several riddles, drops to the inclined surface p below, and eventually to the inclined trough p', from which it iows into any receptacles prepared to receive it. The uncleaned seed passing over the riddles and dropping into the trough p2 will by suitable means, which need not be shown or described, since it 4is common to all such machines, be taken and delivered on the platform k of the conveyer k and from there through the machine again as before. The coarse and waste part operated upon, therefore, is finally delivered to the blower T from the riddles P or from `'the agitators S, that delivered 'from the agitators dropping from the rear end of same fupon the incline M2, and thus down to the blower. From the blower it maybe delivered anywhere in the rear of the machine or on .y so

is regarded as an element distinct from but either side by the pipe t, which may be made flexible. v

In connection with the foregoing description of the Various partsof the machine and the following appended claims it is to be understood that the term feeding device is intended to comprehend the receiving-table C, the toothed endless chain or belt c, mounted thereon, thespreading-wheels d8, and the conveying-belt d4 d5 d6 17, all of these elements or enough thereof to constitute operative means for presenting the straw to the grasping-chain. The term cleaning mechanism is to be understood as including the combs, the head-severing rotary cutter g, and the crushing-rollers H H. The threshing mechanism covers the cylinder m, the.cylinderconcave M M, the rollers O O', the riddles P, the agitators S, the fan r, the blower T, and their associated detail parts. The grasping-chain associated with the cleaning mechanism, its

function being to receive the straw from the feeding device, hold it while being operated elements of the cleaning mechanism.

Brieiiy stated, the operation ofthe machine is as follows: Thebundles of flax are thrown upon the receiving-tableC, where the bands are severed and the bundle somewhat spread over the feeding chain or belt c, with the the con veying-belts d4, (Z5, d6, and dl. These. ,conveying-belts deliver the straw in a continuous swath to the grasping and conveying chains E, E', E2, and E3, which retain it and convey it to the rear end of the machine, where it is delivered to a binding attachment that rebinds the straw into bundles. While held in the grasp of these chains the straw is cleaned and combed, the heads are severed, and the remaining bolls in the top part of the straw are crushed by means of the two sets ofcombs I and I', the cutter g, and rollers H H described. The tops, combings, and cleanings fall to the platform 7a, where the conveyer 7s conveys this material to the forward end of the said platform k and delivers it to the 4crushin,f ,rrollers O O' and the cylinder m. After passing through the said rollers and cylinder the crushed and threshed material passes to the agitator-s S and the riddles P, the coarse portion passing to the agitators and the seed and liner portion passing direct to the riddles. The agitators operate to separate the seed from the threshed straw, the seed working back to the forward end of the table beneath the agitators and falling down on the riddles P. The seed is shaken through the riddles P and eventually to the trough 1o', from which it is delivered into suitable receptacles. `The coarse straw or tops drop from the rear end of theagitators S on the platform M2, where, with the chaff, dac., blown from the material passing through the riddles by the fan r, it'is taken up by the blower T and delivered through the pipe to any desired place. The coarse or uncleaned portion of the threshed material which does not nd its way through the riddles and is not blown away by the fan drops into the trough p2, from where it is taken by any suitable means and delivered upon the platform 7c to be again operated upon by the threshing and cleaning mechanism.
